OBJECTIVES To assess the optimal length of follow-up for patients undergoing both open and minimally invasive pyeloplasties to ensure prompt detection of a recurrent obstruction. There are no standard guidelines on ideal follow-up and imaging post-pediatric pyeloplasty currently. METHODS A retrospective chart review identified 264 patients (<18 years old) who underwent pyeloplasty for uretero...

PURPOSE Copious studies exist regarding the use of stents in pediatric pyeloplasty. Most surgeons use either no stent, an internal (Double-J®) stent or an external transanastomotic pyeloureteral stent. We propose the first known study to compare all 3 methods using a decision tree model that incorporates success rates, complications, patient discomfort and costs. MATERIALS AND METHODS We crea...

OBJECTIVE To determine the presenting symptoms, complications, stone coincidence in the adult patients with primary ureteropelvic junction (UPJ) obstruction seen at King Abdul-Aziz University Hospital, (KAUH) Jeddah, Kingdom of Saudi Arabia, we are also reporting the success rate and long term results of adult pyeloplasty. METHODS We reviewed the records of 34 patients who underwent 37 pyelop...

INTRODUCTION Ureteral atresia is a rare disease usually associated with a non-functioning kidney. Its association with other urinary anomalies is rare. CASE PRESENTATION In this study we discuss the possibility of congenital or acquired etiology of a right imperforate distal ureter. Here we report the case of 11-month-old white boy with a right ureteropelvic junction obstruction. He underwent...

PURPOSE To investigate the effects of the histopathologic pattern of obstructed ureteropelvic junction (UPJ) specimens, including collagen type 3, elastin, fibrosis and Cajal cells, on the outcome of pyeloplasty. MATERIALS AND METHODS Histopathological specimens obtained following Anderson-Hynes pyeloplasty from 52 patients with intrinsic ureteropelvic junction obstruction (UPJO) between Janu...

OBJECTIVE Present the case of a patient with a discontinuous intrabdominal splenogonadal fusion with an associated germ cell tumor. METHODS A case of a man of 29 years with bilateral cryptorchidism and left intra-abdominal discontinuous splenogonadal fusion associated with seminoma as an accidental finding in the context of a robotic pyeloplasty due to ipsilateral ureteropelvic junction sten...

PURPOSE To further explore the feasibility and safety of laparoscopic pyeloplasty (LP) in children with ureteropelvic junction obstruction compared with open pyeloplasty (OP). METHODS PUBMED, Web of science and Cochrane library were searched until Oct. 2014 to find eligible studies. WMD, OR, RD and their 95% CIs were used to estimate the difference. Baseline such as age, gender and crossing v...
